Hey Guys,
I was trying to use the GoalWorldTangentUPP and GoalWorldTangentVPP for the traditional particle system in Maya 2009 and the only value it returns is the zero vector <<0, 0, 0>>. No matter if you are using a poly mesh or NURBS surface it always returns the zero vector. Has anyone been able to get usable results for these Per-Particle attributes?

The GoalWorldNormalPP works just fine.

Also, I have made sure that my mesh has good UV's.

Thanks in advance,
Josh
